Deposit metal alloy onto the special treated ceramic in the ultrahigh vacuum. It gives ultra-low noise figure with low temperature coefficient (T.C.) in four classes: +/-100ppm, +/-50ppm, +/-25ppm/Celsius . Popular requirements of tolerance is 2%, 1% and special needs for +/-0.5%, +/-0.25%, +/-0.1% are classified. Since it is of high precision, temperature stable, low noise, highest reliability and approved MIL-R-10509E specification; it is suitable for following applications: HI-FI stereo, audio & video appliances, electronic calculators, digital and analog computerized system, precision instrument bridge circuits, auto controlled equipment, military devices and space program applications.
